A car-door-operating device comprising wedge-shaped pieces secured to the car-door, 'a shaft or spindle supported onu the underraming in rolling contact with said pieces, hand-wheels mounted on the ends of said said shaft, chains attached to said shaftand wound thereonl whereby the said shaft or spindle can be moved along the said wedges aped pieces-by rotating said hand-Wheel to `open or close the car-door aforesaid.

' 5. In a car, a door carrying wedge-shaped pieces, a shaft supported onthe undcrlt'raming in rolling contact with said pieces, a handlwheel mounted. on said shaft, chains in rolling contact with the said pressed-metal wedge-sha ed pieces, hand-wheels mounted von the en s of said shaft, chains securd to said cross-sills 'attached to the shaft and wound thereon whereby the said shalt can be moved along the said wedge-shaped pieces h y rotating either-of said hand-wheels to open or close1 the 4door aforesaid.

7. A car-dooro].)erating device `comprising 'wedge-shaped pieces of opendaox form with flat or parallel ends secured 'to the car-door, a shaft or spindle mounted in the underlinining in rolling contact with said underi'ra'ining and said pieces and means whereby the said shaft or spindle can be moved along said Wedge-shaped pieces and. under said flat or parallel ends, to open,fclose and loe-l( or support the car-door aforesaid.

8. In a car, a door provided with wedge? shaped stiilieners of open-box form having Hat or parallel ends, a movable support in contact with said wedge-shaped pieces, and means for moving the said support along the said wedge-shaped pieces and under the said lflat or parallel ends, whereby the said door is closed andlocled.

9. In a car, a door provided with wedgeM shaped stiffeners composed of a trapenoidal plate having'integral side and end iianges.

l0. -Ina car, a door provided with wedgeshaped stiHeners composed oi a trapezoidal plate havingl integral side and end llanges and securedv to the door-plate ,along its longitudinal edges,I intermediate stiiliening angles and hinges secured. tothe said doorlate.

1l. In a car, adjacent doors provid-ed with wedge-sha )ed sti'lieners each composed. o'l a trapezoidal plate having integral side and GIIDy framingr in rolling contact with said wedgeshaped pieces and arranged to travel. along the'tapered bottom portion thereof, whereby the said doors maybe opened or closed simul` taneously.
